Key Takeaways
- Cabergoline (brand name Dostinex) is a dopamine D2 receptor agonist that lowers prolactin. It is considered only after blood tests confirm high prolactin and the cause is reviewed.
- H.U.M. Clinic in Bangkok provides generic cabergoline 0.5 mg, at 2,500 THB per strip of 25 tablets. Consultation and testing are not included.
- Low libido, erectile dysfunction and breast tenderness do not confirm high prolactin. They can also come from high estradiol, low testosterone, thyroid or pituitary causes.
- Cabergoline is not an automatic step after trenbolone or nandrolone, and it is not the first-line treatment for estrogen-driven male gynecomastia.
- Cabergoline is a prescription medicine with real side effects. It is started only after physician review and prolactin testing, and not combined with other hormone medications without physician guidance.

Many men searching for cabergoline or Dostinex in Thailand are looking for a way to lower high prolactin, especially after anabolic steroid use, TRT (testosterone replacement therapy), or use of 19-nor compounds such as trenbolone or nandrolone. Some patients may already be taking cabergoline on their own before seeing a doctor.
Dostinex is a well-known trade name for cabergoline. At H.U.M. Clinic, the available product is generic cabergoline 0.5 mg tablets, not branded Dostinex. Cabergoline may be considered for selected men with confirmed high prolactin after medical evaluation and blood testing.
Cabergoline should not be used only because of nipple symptoms, low libido, erectile dysfunction, or fear of “prolactin gyno.” These symptoms can overlap with high estradiol, low testosterone, medication effects, thyroid disease, pituitary disease, or steroid-related hormone suppression.
Men with high prolactin, TRT-related hormone issues, anabolic steroid-related prolactin concerns, low libido, erectile dysfunction, or gynecomastia symptoms can begin with a doctor-supervised TRT and hormone evaluation in Bangkok.
What Is Cabergoline?
Cabergoline is a dopamine receptor agonist. It works mainly by stimulating dopamine D2 receptors, which can reduce prolactin secretion from the pituitary gland.
Cabergoline is different from tamoxifen or raloxifene. Tamoxifen and raloxifene are SERMs used in selected cases of recent active male gynecomastia. Cabergoline is not a SERM and is not a general gynecomastia medication. It is mainly used when prolactin is actually elevated and the cause has been reviewed.
Official US cabergoline prescribing information describes cabergoline as a prescription medication for hyperprolactinemic disorders and includes important safety warnings.
Cabergoline for High Prolactin in Men
High prolactin in men can cause low libido, erectile dysfunction, infertility, low testosterone-like symptoms, reduced orgasm quality, nipple discharge, breast tenderness, or gynecomastia-like symptoms in some cases.
However, prolactin should be interpreted carefully. A mildly elevated prolactin result can occur from stress, poor sleep, recent sex or exercise, blood draw timing, certain medications, hypothyroidism, kidney disease, or macroprolactin. Very high prolactin may raise concern for a pituitary cause such as prolactinoma.
The Endocrine Society hyperprolactinemia guideline (2011) recommends proper diagnosis and management of hyperprolactinemia and supports cabergoline as first-line treatment for prolactinoma in appropriate patients.
High prolactin can also lower LH and FSH, the signals that tell the testes to make testosterone, so some men first notice it as low testosterone. This is why the Endocrine Society testosterone therapy guideline recommends checking prolactin in men who have low testosterone with low or normal LH and FSH. When high prolactin is the cause, treating it may improve testosterone without TRT. If testosterone stays low after the cause is addressed, doctor-supervised testosterone replacement therapy (TRT) can be discussed as a separate, monitored option.
Cabergoline, Trenbolone, Nandrolone, and AAS Use
Some men search for cabergoline after using trenbolone, nandrolone, or other anabolic-androgenic steroids because they are worried about high prolactin, sexual dysfunction, or gynecomastia during or after a cycle.
H.U.M. Clinic does not recommend unsupervised anabolic steroid use or self-directed cabergoline use. In steroid-related cases, symptoms may come from multiple causes at the same time, including high estradiol, suppressed LH and FSH, low endogenous testosterone, abnormal prolactin, altered dopamine signaling, sleep disruption, mood effects, or post-cycle hormone suppression.
Cabergoline should only be considered if prolactin is confirmed to be elevated and the clinical picture supports treatment. Taking cabergoline without confirming prolactin can lead to unnecessary side effects and may delay proper diagnosis.
For high prolactin linked to a medicine, the Endocrine Society guideline suggests stopping or changing that medicine when possible and rechecking prolactin, and not treating a raised result that causes no symptoms. The same cause-first approach applies to steroid-related cases, where cabergoline use also falls outside the indications listed in the US prescribing information.
Men with steroid-related hormone suppression may also need hormone and testosterone blood testing to assess testosterone, estradiol, LH, FSH, prolactin, hematocrit, liver function, lipid changes, and fertility-related concerns.
Does Cabergoline Treat Male Gyno?
Cabergoline is not usually the first-line treatment for typical estrogen-driven male gynecomastia. Most recent, tender gynecomastia during TRT or anabolic steroid use is more often evaluated through testosterone, estradiol, medication exposure, breast exam, and timing of symptoms.
If prolactin is normal, cabergoline is unlikely to be the main treatment. If prolactin is high, treatment depends on the level, cause, symptoms, medication history, and whether pituitary evaluation is needed.
For patients whose main problem is recent nipple tenderness or glandular gynecomastia, male gynecomastia treatment options such as tamoxifen may be more relevant after medical evaluation.
Cabergoline Price at H.U.M. Clinic
H.U.M. Clinic provides generic cabergoline for selected male patients after physician consultation and blood testing.
Current product option:
- Generic cabergoline 0.5 mg tablet
- 25 tablets per strip
- Price: 2,500 THB per strip
This price does not include doctor consultation, blood testing, pituitary MRI when needed, follow-up visits, or other medical service fees.
Patients searching to buy cabergoline or Dostinex in Thailand should not choose treatment based on price alone. The key step is confirming whether prolactin is truly elevated, why it is elevated, and whether cabergoline is safe and appropriate.
Patients can book a consultation with our doctor for prolactin testing, hormone review, and treatment planning.
Blood Tests Before Cabergoline
Before starting cabergoline, H.U.M. Clinic may review symptoms, medication history, TRT or anabolic steroid use, fertility goals, sexual symptoms, headache, visual symptoms, and previous prolactin results.
Blood testing may include prolactin, repeat fasting morning prolactin when appropriate, macroprolactin if suspected, total testosterone, free or calculated free testosterone, SHBG, LH, FSH, estradiol, TSH, free T4, liver function, kidney function, and other tests when clinically indicated.
If prolactin is very high, persistent, unexplained, or associated with headache, visual field symptoms, or low pituitary hormones, pituitary MRI or endocrinology referral may be needed. The Pituitary Society prolactinoma consensus statement (2023) provides clinical context on prolactinoma diagnosis, imaging, dopamine agonist treatment, and follow-up.
Side Effects and Safety
Cabergoline can cause side effects and should be used only under medical supervision. Possible side effects include nausea, dizziness, headache, fatigue, constipation, low blood pressure, sleepiness, mood changes, impulse-control symptoms, and nasal congestion.
More serious but less common concerns include heart valve problems, pericardial or pulmonary fibrosis, psychiatric symptoms, and worsening hypotension. Patients with uncontrolled psychiatric illness or unexplained fainting may need additional review before treatment.
Patients should not combine cabergoline with anabolic steroids, TRT dose changes, aromatase inhibitors, SERMs, or other hormone medications without physician guidance. Using multiple hormone medications without monitoring can make prolactin, estradiol, testosterone, fertility, mood, and cardiovascular safety harder to manage.
Who Should Not Take Cabergoline?
The US prescribing information lists cabergoline as contraindicated in people with uncontrolled high blood pressure, a known allergy to ergot-derived medicines, a history of heart valve disease, or a history of fibrosis (scarring) of the lungs, pleura, pericardium, or retroperitoneum. It also advises a heart evaluation, including an echocardiogram (heart ultrasound), before treatment starts.
Heart valve problems have mainly been reported in people with Parkinson’s disease taking much higher daily doses than those used for high prolactin. The Endocrine Society guideline notes that people on typical prolactin-lowering doses likely do not need regular echocardiogram screening, so your doctor will advise on heart checks based on your dose, treatment length, and medical history.
During treatment, tell your doctor about any new gambling, spending, or sexual urges, as these can be side effects of cabergoline.
How to Get Cabergoline at H.U.M. Clinic
Cabergoline at H.U.M. Clinic is prescribed only after a doctor’s assessment. The process usually follows four steps:
- Book a consultation at H.U.M. Clinic Asoke (Exchange Tower, connected to BTS Asok and MRT Sukhumvit) or H.U.M. Clinic Thonglor (Hotel Nikko Bangkok, near BTS Thong Lo). See our Bangkok locations or book an appointment online. Walk-ins are welcome, but booking ahead reduces waiting time.
- Your doctor reviews your symptoms, medication history, TRT or anabolic steroid use, and any previous prolactin results.
- Blood samples are collected at the clinic to check prolactin and related hormones. Selected rapid tests are done on site, and other tests are processed by a partner laboratory.
- If cabergoline is appropriate, your doctor prescribes generic cabergoline 0.5 mg (2,500 THB per strip of 25 tablets) and plans follow-up visits and testing.
If prolactin is normal or another cause is found, your doctor will explain other options instead.
